Industrial Practice of Biohydrometallurgy in Zambia
2015Bio-hydrometallurgy technology was applied for the extraction of copper from the raw ores of Chambishi Mine in Zambia. A copper extraction of 93.29% was obtained for small scale column bioleaching within 63 days, while a copper extraction of 89.05% was achieved for large scale column bioleaching in 90 days, thus confirming the amenability of the raw ...

Present and future commercial applications of biohydrometallurgy
Hydrometallurgy, 1999Modem commercial application of biohydrometallurgy for processing ores became reality in the 1950s with the advent of copper bioleaching by what was Kennecott Copper Corporation. Early application entailed dump leaching of low-grade, low-value, run-of-mine material.

Spectroscopic and Microscopic Investigation for Biohydrometallurgy
Advanced Materials Research, 2015In a process of bioleaching of sulfides, the surface of target mineral is sometimes covered with intermediates and final products to interfere the extraction of metal. Understanding characterization and formation order of secondary minerals, which are responsible for passivation, is a key to resolve the passivation.

Airlift Reactors: Characterization And Applications In Biohydrometallurgy
2007Over the last decade biooxidation for the pretreatment of refractory sulfidic gold concentrates and the bioleaching of copper have been applied with increasing frequency. In addition to heap-leach facilities for the bioleaching of copper, several biotank oxidation plants are also operational for the pretreatment stage in the processing of refractory ...
